1116 St. Ivo of Chartres died. He was one
of the most notable bishops of France at the time of the Investiture struggles
and the most important canonist before Gratian. Gratian was a legal scholar and
the founder of the science of canon law, which is the body of law based on the
legislation of the councils (both ecumenical and local) and the popes, as well
as the bishops (for diocesan matters) in the Roman Catholic Church
